I’m currently doing monthly DCAs to FSMone RSPs VT, HK tracker fund and Nikko S-reits ($1200 total) and StashAway 30% risk index $300. Should I switch?

In my honest opinion, I would recommend you in reviewing the underlying assets of the portfolio of the Stashaway and Syfe to see if there's any overlap.

Majority of Equity100+ exposes investor to United States which I believe that VT has covered significantly. As VT is a Total World ETF, I believe that most of the stocks in the world would have already been covered in that ETF. Therefore, I think that Stashaway at 30% risk is unnecessary because it should have already been covered by VT already. This is unless you want the exposure to China Tech ETF, Bond or Gold components.

As for Nikko S-Reit to Syfe REIT+, I just saw the underlying assets of the former, the decision for you is whether you want to focus on SReit using REIT+ or some international reit exposure with the former. I think it is really a tough decision to make but I believe it is really a personal preference of where and how much to diversify into different geographical reits.

If I were you, I will keep the VT, Tracker Fund (though I think it might have already been covered in VT) and to switch for a lower risk portfolio for Stashaway to hold Bonds and Gold for hedging purposes and as for REIT i would really go for Syfe+ as I prefer S-REIT than international exposure to other markets' reits.
